Not consistently, but once every 10 tries or so, I get the following backtrace which does not seem to originate in my own code: Can not modify the buffer right now, there are active subbuffers. -:1:

Scope runtime bug in Pike 8.0 and 8.1
by Stephen R. van den Berg 08 Jun '19

08 Jun '19

-------------------------------------------------------- class foo { #if 1 protected int bar; // Does not work (and is a bug) #else int bar; // Does work #endif this_program other; protected void create() { other = this; other->bar = 1; } } object x = foo(); -------------------------------------------------------- This gives a runtime error which seems incorrect to me. Flipping the #if causes it to run flawlessly. Is this a problem in Pike, or are my expectations too high? -- Stephen.
